The smoke-test runbook step 3 promised 'AI should greet you and
offer to scaffold something' but the empty-thread state was just
a logo + tagline. Replaced with:
- Project-aware greeting ('Welcome to <project name>.')
- One paragraph that names the affordances (paste brief, drop
link, pick a starter)
- Four click-to-prefill suggestion chips that map to the smoke
test entry points: scaffold a todo app, walk through a scope
doc, plan a new idea, tour Vibn's capabilities.
Chips set the input value; user still hits send to commit.
